High-Performance Commercial HVAC Systems for Marin County and San Francisco

Choosing the right HVAC system for your commercial property ensures comfort, efficiency, and cost savings. At Bay Air Heating & Cooling, we install and service cutting-edge HVAC systems for businesses, from offices to industrial facilities.

Ductless Mini-Split Solutions for Flexible Comfort

Ductless mini-split systems offer a versatile, energy-efficient alternative for commercial properties without existing ductwork. These systems feature an outdoor unit connected to multiple indoor units (wall- or ceiling-mounted), allowing precise temperature control for individual zones like offices, retail spaces, or server rooms. 

Key Features:

High Efficiency:

Variable-speed compressors adjust output, saving 20-30% on cooling and 40-50% on heating costs.

Zoned Comfort:

Independent controls for each indoor unit optimize occupant satisfaction.

No Ductwork Needed:

Eliminates energy losses from leaky ducts, which can waste 20-30% of energy.

Quiet Operation:

Low-noise indoor units, ideal for customer-facing spaces.

Rooftop HVAC Units for Robust Performance

Packaged rooftop units (RTUs) are a durable, all-in-one solution for commercial properties with flat roofs, such as retail stores, warehouses, or schools. These systems house heating, cooling, and ventilation components in a single unit, simplifying maintenance and installation. 

Key Features:

  • Energy Efficiency: ENERGY STAR-certified RTUs save 10-30% on energy costs with high SEER ratings. 
  • Solar Compatibility: Optional solar-powered models further reduce operating costs. 
  • Smart Controls: IoT-enabled thermostats optimize performance, saving an additional 5-10%. 
  • Reliability: Designed for heavy-duty use, delivering consistent comfort year-round.
